I've been going over my Dad's (W5JHJ SK) Globe Champ 350 getting it ready to
put back on the air. Every eloctrolytic capacitor had been replaced by him as
they all look new and modern. The paper capacitors have been left as is. He
replaced the oil-filler filter caps with much larger electrolytics. All of the
resistors look brand new and as far as I can see nothing is amiss. The old
selenium rectifiers for the bias supply were replaced long ago and I see evidene
of some other minor part substitutions. He was the only owner of the unit, so
all changes are his. I know that he also disabled the SSB position of the mode
switch. Also, noneof the knobs on th efront are original -- one may have broken
at some point and he then chose to replace them all.
There is one minor part that needs replacing, however. On the rear of the
transmitter, in the lower right corner (facing the back of the unit) is a
switched AC receptacle, just above the plug that controls the mute line for the
receiver. While I was moving the transmitter that receptacle was damaged. He
used it to plug in a squirrel-cage fan to aid cooling the transmitter and power
transformer. I have looked in my Mouser catalog for a replacement but haven't
found anything that is a drop-in fit. The opening is 3/4" wide, 3/8" tall with
holes 1 1/8" apart for 6/32 screws that can be used for mouting ears. I've
looked carefully at the receptacle and have found no part numbers. The only
markings I can find are the manufacturer's name "KULKA" and the rating"125VAC
15A" on one face and the UL insignia in the center of the front, between the two
slots that receive the prongs of the plug. It's an otherwise standard, 2-pin AC
receptacle. It's made of Bakelite and is probably original. I could probably
epoxy it back in in a pinch, but I truly want to avoid that and do this right.
Anybody know where I can find another one of these?
